A flushing ring is a device used to clean and maintain pressure measurement instruments by flushing out residues and preventing blockages in process lines.

Freture's is prominent leading Flushing Ring manufacturer in Mumbai, India. A flushing ring is a metal donut-shaped component placed between the seal and the customer's process connection. It features threaded ports (¼-inch or ½-inch) for diaphragm surface flushing during cleaning. Flush rings generally adhere to gasket dimensions specified by flange standards like ASME B16.5 or EN 1092-1. In ASME B16.5, for RF facing, dimensions are consistent across pressure classes for a given size. For instance, a 2″ flush ring fits class 150 through 2500 with identical dimensions. However, different facings require unique dimensions per size and rating.
Flushing rings, known by various functional names, share a similar basic design. Positioned between a diaphragm seal and the process nozzle, they are commonly referred to as "Flushing Ring" due to their role in clearing process medium buildup from the diaphragm. These rings typically feature one or two threaded flushing ports on their sides, which can either be plugged or connected to a drainage system. This design allows for system flushing without disconnecting the remote seal from the process flange. The pressure chamber of the flush ring can be vented or drained and filled with cleaning detergent for effective diaphragm cleaning.
